The Hyundai Series 9 compaction rollers product line includes four single-drum models designed primarily for soil and aggregate compaction, and two compact tandem-drum models designed primarily for asphalt paving and maintenance. All six models offer 360-degree visibility for the operator.

The Hyundai Series 9 compaction roller models are powered by highly fuel-efficient and reliable Perkins and Deutz diesel engines.

Single-drum models for soil compaction

The single-drum HR70C-9, HR110C-9, HR120C-9 and HR140C-9 models are designed primarily for soil compaction applications. The compaction drum is available as a smooth or pad-foot surface. The optional pad-foot kit is designed for easy installation.

Hyundai’s unique HA control delivers a continuous tractive effort at the axle and drum for automatic adaptation to various soil types and conditions. Dual frequencies and amplitudes provide two levels of vibration for efficient surface and deep soil compaction.

The Hyundai Series 9 single-drum roller models range in horsepower from 84 to 140 (61.5 to 103 kW), in operating weight for smooth-drum configuration from 15,652 to 30,644 lb (7 100 to 13 900 kg), in drum width from 67 to 83 in. (1,700 to 2,100 mm), and in gradeability without vibration from 45 to 50 degrees.

Compact tandem-drum models designed for paving

While the Hyundai HR25T-9 and HR30T-9 tandem-drum roller models are primarily designed for aggregate paving applications, contractors also may use these compact machines for soil compaction. Both models feature front and rear scrapers to keep the drums free of material build up. They also provide 55-gal.-capacity water-spray systems that can sprinkle both the pavement surface and the drums, with operator-adjustable sprinkling intervals. Each model offers the largest drum in its weight class for optimum compaction results.

The HR25T-9 model has an operating weight of 5,400 lb. (2 450 kg) and drum width of 40 in. (1,016 mm). The HR30T-9 model has an operating weight of 6,600 lb. (2 994 kg) and drum width of 50 in. (1,270 mm). Both models achieve maximum gradeability without vibration of 35 degrees, and are powered by a Deutz D 2011 L2 I diesel engine rated at 30.2 hp (22.5 kW).

Designed for easy maintenance and serviceability

All Hyundai Series 9 compaction roller models are designed with serviceability in mind. Engines and other components are easily accessible, thanks to the wide opening engine hood that provides 270-degree, front and side access. The low-maintenance articulated joint features Teflon-coated bearings to eliminate the need for frequent greasing. The vibration systems are designed for long life and reduced maintenance requirements.
The Hyundai Series 9 compaction roller models carry a standard two-year, 2,000-hour warranty.
